<p>
      A new state, GTK_STATE_FLAG_CHECKED, has been added for checked states
      of radio and check buttons and menuitems. Applications that are using
      GTK+ styles without widgets will need adjustments.
    </p>
<p>
      Adwaita is now the default theme on all platforms.
    </p>
<p>
      The icon theme code has become a little pickier about sizes and is not
      automatically scaling icons beyond the limits defined in the icon theme
      unless explicitly asked to do so with GTK_ICON_LOOKUP_FORCE_SIZE.
    </p>
<p>
      GTK+ now includes an interactive debugger which can be activated with
      the keyboard shortcuts Ctrl-Shift-d or Ctrl-Shift-i. If these shortcuts
      interfere with application keybindings, they can be disabled with the
      setting org.gtk.Settings.Debug.enable-inspector-keybinding.
    </p>
<p>
      Most widgets have been ported to use the new gesture framework internally
      for event handling. Traditional event handlers in derived widgets are still
      being called.
    </p>
<p>
      Using GTK+ under X11 without the X Render extension has been observed
      to be problematic. This combination is using code paths in cairo and
      graphics drivers which are rarely tested and likely buggy.
    </p>
<p>
      GtkTextView is now using a pixel-cache internally, and is drawing
      a background underneath the text. This can cause problems for applications
      which assumed that they could draw things below and above the text
      by chaining up in the ::draw implementation of their GtkTextView subclass.
      As a short-term workaround, you can make the application apply a
      custom theme to the text view with a transparent background. For
      a proper fix, use the new ::draw_layer vfunc.
